External Email - Use Caution Hello Adam, I hope you saw the previous email I sent you about changing SUBJECTS_DIR to be different from the default.   Just wondering if you did that for SUBJECTS_DIR before running the recon-all. - R.

Calculating Distortion in mris_flatten()
by Sarah Lavelle 28 Nov '22

28 Nov '22

External Email - Use Caution Hi Bruce, Thank you very much for your response. I would like to calculate this distance error for specific regions on the flatmap after the transformation, so I can formulate cuts to minimize it for the region I am interested in. Do you have any suggestions on how I can do it? From reading your paper : *Fischl B, Sereno MI, Dale AM. Cortical surface-based analysis. II: Inflation, flattening, and a surface-based coordinate system. Neuroimage. 1999 Feb;9(2):195-207. doi: 10.1006/nimg.1998.0396. PMID: 9931269, *I understand that distances are calculated using the corrected *Dijkstra **algorithm* as an estimator of geodesic distances. In your response, you said that the distance error is calculated with: *100 * (mean(abs(distance error)) / mean(original_distances))* Are the *original_distances = the geodesic distances (gd) calculated (using the Dijkstra algorithm) for each vertex on the inflated surface*? Is the *distance error = (gd on the flatmap) - (gd on the inflated surface)?* Do you know how I can do this in matlab for just *one region using the DKTaltas*? for example, the superior frontal? Any help would be greatly appreciated!

recon-all failing to generate wm surface
by Christopher Mcnorgan 28 Nov '22

28 Nov '22

External Email - Use Caution A student and I have independently been trying to reconstruct a dataset. We've tried it a couple different ways using either an additional FLAIR or a T2 image and always hit a point where the process halts because of a missing surface file: Loading lh.white surf error: No such file or directory error: MRISread(/home/cpmcnorg/VMP/FS_002/surf/lh.white): could not open file This has happened when running just the autorecon1 step or both autorecon1 and autorecon2. I'm using freesurfer 7.2.0 on a linux computer, and my student is running 7.3.2 on a Mac. In my most recent test, I ran recon-all -autorecon1 -autorecon2 -i <path to T1 file> -T2 <path to T2 file> -subjid <ID> and I have several surface files (e.g., ?h.orig and even ?h.white.preaparc) but not the ?h.white surface. I'm unclear what's causing the recon-all script to look for the wm surface before it's been created.

TRACULA: domainname: Command not found.

External Email - Use Caution DearFreesurfer developers, when trying to run trac-all -prep I am running into this error gbw-d-m0128:DIFFUSION r0755008$ trac-all -prep -c /Users/r0755008/Desktop/mri_data/TRACULA/TRACULA_CONFIGURATION_FILE.txt domainname: Command not found. Too many ('s. ERROR: Syntax error in configuration file /Users/r0755008/Desktop/mri_data/TRACULA/TRACULA_CONFIGURATION_FILE.txt I checked the file but there seem to be no errors in the ('s. This error has previously been encountered https://secure-web.cisco.com/1sKX4EXSdl-lzzKBfb369ful1KJMpWkExgYjXUfdMyAgEi… but there is no solution proposed for the facts that the domainname command is missing from my mac in the /usr/bin folder. What can i do to solve this error. In the attachments you can find the tracula config file if this would be helpful. Thank you for the help. Kind regards, Ward Deferm
